Levels of e-Commerce Sophistication

Level Characteristics

Primitive Static web pages or ‘brochure ware’

Searchable site with dynamic pages such as an online catalogue

Integration with operational databases, e.g. inventory searching, package tracking, job postings

Customer transaction through the Internet, e.g. selling products and services, buying and selling shares, applying for loans

Advanced Full electronic commerce (i.e. integrated fulfillment cycle of ordering, shipping, billing)

The Reasons for Implementing e-Commerce

• A Customer’s standpoint:– Increase in demand for choice (product depth, global

reach, price choices)– Demand for information (detailed product information,

inventory, order status)– Demand for interactive, online support– Avoidance of travel and parking difficulties for

consumer e-commerce– Elimination of time constraints (that is, opening hours

or delays between placing an order and delivery)

The Reasons for Implementing e-Commerce

• A business customer’s standpoint:– Lower purchasing overhead – especially for small

value and repeat orders– Greater choice (greater product depth and global

reach)– Faster fulfillment cycle time (ordering, shipping,

billing)– Greater ability to supply information (inventory, order

status, etc)– Lower cost than EDI

Exp. Dell Computers

The Reasons for Implementing e-Commerce

• A supplier’s standpoint:– A global reach, leading to more orders– Reduced administration overhead– Integration between back office and online ‘shopping’

activities– Integration of online ‘shopping’ activities with

database marketing– Less need for distribution via channel

– Reduced working capital (inventory)
